It can be tempting to let some players play multiple characters. Or to switch from one character to another. It can solve many
of the otherwise awkward problems of characters not being where the action is and so their players having to sit out large parts of
the game. Or of a character moving from a foreground role to a background supporting role, leaving them not much to do any more.

Just make sure the players know that this is done by your grace, and not at the drop of a hat.

Then again... it could be fun.
